semi No. 758,758.

T 0 all whom it may concern i Be it known that we, Wneonn Hmsvnnn andCHRISTIAN HANSEN, citizens ofthe United States, residing at San Diego,in the county of San Diego and State ofCalifornia, have inventedycertain new and useful Improvements in Combination Hose-Plugs, of whichthe following is a s cification.

Our invention re ates to improvements in plugs for hose or any otherstyle of tubing of` a soft and pliable material, and more particularlytobeused for plugging the ends thereof, and the objects of our inventionare, first, to provide a lug for hose or tubing of a soft andpliabe-material `to close the ends thereof; second, to provide a plugthat will clampfonto v,the lhose and .stand great pressure, and third,to provide such a 'plug that is simple of construction, durable, easilyinstalled, easily removed and very eiiicient.

With theseand other objects in view as will hereinafter appear, ourinvention consists of certain novel features of construction,combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claims, referencebeinv had to the accompanying drawings andato the characters 0freference thereon, which form a specification, in which: r

Figure 1 is a sectional view of our combination hose plu complete shownmounted on the end of a Iiose, Fig. 2 is a detail view of the movablepressure part, Fig. 3 is a detail view of the expandin bushing and Fig.4 -is a detail view of the t imble. L

Similar characters of reference refer to similar parts throughout theseveral views.

The combination plug consists of a movable pressure part 2, theexpanding bushing 3, the thimble 4, the washer 5 and the nut 6. Thethimble 4 is adapted to tit over the end of the hose and is rovided witha plurality of inwardly extending ridges 4, as shown, preferablyintegral therewith, adapted to retain the hose or tube when the same isexpanded withinl said thimble L It is provided withl aninwardlyextending flange 4b for retainingand supporting the expanding bushing3.- The expanding bushing 3 is shaped as shown best in Fi 1 and is madeof softinetahpreferablylea and adapted to -fectual plug capable ofwithstandin part of this fit the inner surface of the hose. The movablepressure part 2 is tapered and shaped as shown best in Fig. 1 and isprovided with a threaded spindle 2a adapted for the nut 6 which isscrewed against a washer 5 which in turn has its bearing on sleevefiange 4b. When vthe nut 6 is tightened against the washer .5 it drawsthe pressure plug 2 into the expanding bushing 3, which expands andpresses the material of the hose or tube between the inwardly extepdingridges 4 and against the inner surface of the thimble 4 forming a verytight connection.

Though we have shown and described a 'particular construction,combination and arrangement of parts, We do not wish to be limited tothis particular construction, combination and arrangement of parts, butdesire to include in the purview of our invention the construction,combination and a1'- rangement substantially as set forth in theappended claims.

It will be readily seen that with the construction as shown there isprovided a hose or tubing which provides a simple but efgreat pressure,and that it is durable an y easily placed on or removed from the hose.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is: I' 1. In a combination hose lug, thecombination of a thimble mounte a hose provided with a plurality ofinwardly extending ridges, a tapered soft metallic bushing fitting theinner surface of said hose and a tapered pressure part adapted to bepressed into said bushing and spread the same, provided with a threadedspindle, and a nut and washer adapted to screw onto said spindle andagainst the end of said thimble, adapted to force said pressure partinto said bushing.

2. In a combination hose plug, the comJ bination with a hose, of athimble mounted over the end of a hose provided with a plurality ofinwardly extending ridges, a' tapered soft metallic bushing fitting the'inner surface of said hose, and a tapered pressure part adapted to bepressed into said bushing and spread the same, provided with a threadedspindle, and a nut and washer Btl over the end of adapted to screw ontosaid spindle and subscribed our names in the presence of two against theend of said thimbie, adapted to subscmbing Witnesses.

force said pressure part into said bushing, WUGBOLD HUISZELD. adapted tocompress the end of the hose be- CHRISTIAN HANSEN.
